Thanks. I didn't want to wander into a discussion of error recovery in general - I'm not writing a paper, just wanted something practical to use or implement - but ANTLR is probably the exception.
I think I got the gist of it from the first page of the google search 'error recovery ANTLR'. It does look decent, though I'd want to try its automatic resynching with a real grammar and test cases before making any judgements.
